Advantage of the present utility model is:
(1) this coal gas mixing arrangement, can be used for the mixing of two or more coal gas media, adopt the traditional single heavy caliber control valve group of the small-bore control valve group of many groups replacement in parallel, can realize many combination flexible operatings, the scope of regulating tolerance is wide, the precision height has particularly solved the adjusting difficulty of conventional hybrid device when micro-demand;
(2) this coal gas mixing arrangement resolves into the small-bore control valve group of many groups with the single heavy caliber control valve group of every kind of coal gas, compose in parallel, and the long-pending sum of the pipeline section after the parallel connection is more than or equal to the sectional area of gas main, the gas supply in the time of can guaranteeing user's greatest requirements.
Therefore, the utility model coal gas mixing arrangement can come into operation according to heating furnace baker, separate unit, many come into operation, the gas using quantity of different times such as user maintenance is selected the control valve group that is more suitable for, obtains stable, the accurate mixed gas of flow and calorific value.
Description of drawings
Fig. 1 is the schematic diagram of the utility model coal gas mixing arrangement.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described.
With reference to shown in Figure 1, be the schematic diagram of the utility model coal gas mixing arrangement.As seen from Figure 1, with respect to coal gas mixing duct of the prior art, the utility model coal gas mixing arrangement is composed in parallel by many groups of small-bore control valve groups, specifically, comprise at least two group main lines, be parallel with the lateral of two groups of above diameters between the both ends of above-mentioned main line respectively less than described main line diameter, also be that above-mentioned main line forms by the lateral of many group diameters in parallel between its both ends less than described main line diameter, above-mentioned lateral upper edge flow of gas direction is disposed with stop valve, flowmeter 3 and control valve 4.Above-mentioned stop valve comprises butterfly valve 1 and blank-plate valve 2.
In the preferred embodiment, specifically comprise two groups of main lines: first main line 10 and second main line 20, being respectively applied for provides two kinds of different coal gas medium A and B.
First main line 10 is formed by two group of branches pipelines in parallel between its both ends 101, is respectively first lateral 11 and second lateral 12.
Second main line 20 is also formed by two group of branches pipelines in parallel between its both ends 201, is respectively the 3rd lateral 21 and the 4th lateral 22.
Coal gas medium A and B supply three users after mixing, but the utility model is not limited to this.For example, the coal gas medium that mixes at needs can also again be provided with a main line during more than two kinds more, simultaneously, between the main line both ends the concrete quantity of lateral in parallel also can carry out different settings according to actual needs.
Preferably, the sectional area sum of the lateral of above-mentioned each main line is respectively more than or equal to the sectional area of each main line.Also promptly, be meant in this specific embodiment: the sectional area sum of first lateral 11 and second lateral 12 is more than or equal to the sectional area of first main line 10; The sectional area sum of the 3rd lateral 21 and the 4th lateral 22 is more than or equal to the sectional area of second main line 20.And the diameter of the diameter of above-mentioned first lateral 11 and second lateral 12 or the 3rd lateral 21 and the 4th lateral 22 can be identical or different.
Below in conjunction with the concrete course of work the utility model coal gas mixing arrangement is further detailed: after only user I begins to put into operation, gas using quantity is few, for ease of regulating the calorific value precision of consumption and assurance mixed gas, by regulating the control valve group, select for use first more small-bore lateral 11 and the 4th lateral 22 to carry out work, and the valve of second lateral 12 and the 3rd lateral 21 all is in closed condition, control valve in first lateral 11 and the 4th lateral 22 can carry out aperture control according to flowrate proportioning, thereby guarantees mixed gas flow and calorific value precision.When user I and user II move simultaneously, by regulating the control valve group, select for use second lateral 12 of larger caliber and the 3rd lateral 21 to carry out work, close the valve in first lateral 11 and the 4th lateral 22.When user I, II, III came into operation, this moment, gas using quantity reached maximum, and all lateral 11,12,21,22 all comes into operation.
Through this kind configuration mode, the coal gas requirement in the time of can satisfying user's different times, and be easy to regulate, mixed gas flow and calorific value are stable.
By foregoing description as can be seen, coal gas mixing arrangement of the present utility model can control to adjust the aperture of valve according to gas flow.The coal gas proportioning that mixed gas is different according to the different needs of calorific value, this proportioning are finally realized by the aperture that changes control valve by the control valve group.When the mixed gas requirement hour, can preferentially select control valve group on a certain group of small-bore pipeline in the parallel connection to regulate and mix, other control valve group is in reliable dissengaged positions, when user's gas using quantity is big, can select control valve group on the pipeline of the larger caliber in the parallel connection to regulate and mix, supply is regulated in selection also capable of being combined, when user's gas using quantity reaches maximum, all pipelines all come into operation, this device has increased the flexibility ratio that coal gas mixes, increased adjustable range simultaneously, and be easier to regulate.
With mill heating furnace user is example, consumption is less during the heating furnace baker, the operation initial stage, the heating furnace that comes into operation is less, consumption is also less, this moment is by regulating the control valve group, adopt small-bore pipeline can reach more accurate flow and calorific value, and gas flow and calorific value fluctuation are less, along with the continuous increase of gas using quantity, can increase pipeline or select the pipeline of larger caliber to carry out work, when treating that all heating furnaces all come into operation, it is maximum that consumption can reach, and need all pipelines all to devote oneself to work this moment.
The mill heating furnace is because the difference of workshop section, the cycle of coming into operation is often very long, but the pipeline and the mixing arrangement of supply mixed gas need once build up, for not influencing user's operate as normal, select for use this utility model coal gas mixing arrangement can reach better effect, and operate more flexible, the mixed gas quality height of supply, benefit is obvious.
Need to prove; the above only is preferred embodiment of the present utility model; rather than to the qualification of technical solutions of the utility model, any the utility model technical characterictic being equal to of being done replaced or corresponding improvement, still within protection domain of the present utility model.
